A kernel density estimator for data on the polysphere S d 1 × × S d r \mathbb{S}^{d_1}imes\cdotsimes\mathbb{S}^{d_r} , with r , d 1 , … , d r ≥ 1 r,d_1,\ldots,d_r\geq 1 , is presented in this paper. We derive the main asymptotic properties of the estimator...
核密度估计(kernel density estimation)是在概率论中用来估计未知的密度函数,属于非参数检验方法之一,由Rosenblatt (1955)和Emanuel Parzen(1962)提出,又名Parzen窗(Parzen window) 灵感来自于直方图 纵轴:直观理解就是每个小区间中包含的样本数占总样本的比例 ...
Kernel density estimation 核密度估计 设 (x_1, x_2, ..., x_n) 是从某个单变量分布中抽取的独立同分布样本,在任何给定点x具有未知密度f。俺想估计这个函数f的形状。它的核密度估计量是 \widehat{f}_h = \frac{1}{n}\sum\limits^{n}_{i=1}K_h(x-x_i) = \frac{1}{nh}\sum\limits^{...
【转载】核密度估计(kernel density estimation) Table of Contents 有一些数据,想“看看”它长什么样,我们一般会画直方图(Histogram)。现在你也可以用核密度估计。 什么是“核” 如果不了解背景,看到“核密度估计”这个概念基本上就是一脸懵逼。我们先说说这个核 (kernel) 是什么。

核密度估计(kernel density estimation) 简单理解:就是让原本离散的点形成平滑的密度分布情况 最简单的密度分布就是直方图,可以估计出离散点的分布情况,设置不同的带宽会形成不同的分布直方图,可以理解为不同的和密度函数,下图就是对应的例子。虽然离散点不变,但是划分规则不同,因此显示出完全不同的分布,这也说明对于...
